What to do when you Run into Grow Room Cooling Problems

There’s not much worse for an indoor grower than grow room cooling problems. The cooling system is a crucial part of the grow room vital systems. Grow rooms can quickly become extremely hot if their AC system malfunctions.

I ran into some issues with one of my flower room AC systems recently, and I opted to get a wireless thermometer system for my grow rooms from Acurite. It has the ability to send text messages and emails if one of the set parameters is reached. It is nice to see what the current temps and humidity levels are at while elsewhere.

There are more advanced systems that are available from Smart Bee Controllers and other companies. I have yet to work with these controller systems, but I will update the article once I get a chance to work with them.

I recommend having a good protocol if the AC system were to stop working properly. The first thing I do when walking into a hot grow room is access the situation. If the grow room is above 100 degrees then I will turn off the lights immediately, and open the doors with fans pointed out to immediately exhaust the heat. If it is below 100 degrees then I will usually turn off a majority of the lights, and turn down all the light ballasts to the lowest settings.

While having the light schedule interrupted is bad. Having your buds melt away is equally as bad in my book. So I usually will choose the lesser of the two evils. Opening doors and exhausting the heat is the quickest way to remove the heat from the room. Manually turn on any exhaust fans if you have them installed in the room.

Depending on your type of AC system. You could possibly solve your problem by resetting the circuit breaker your system. This usually solves about half of the issues that I will see when coming up to a typical mini split problem in a grow room.
